柴石滩水库溢洪道高边坡稳定性分析与加固治理

On stability analysis and reinforcement of spillway high slope for Chaishitan reservoir

柴石滩溢洪道高边坡总高度接近220 m。存在全强风化圈和不利软弱结构面,在施工中由于支护等不合理施工程序和受雨水及地下水的影响,局部地段沿软弱结构面出现拉裂缝和滑坡现象。为了保证边坡和工程的安全,及时采用了抗滑桩等综合加固治理措施,加固治理效果较好。

The spillway high slope of Chaishitan reservoir approaches 220m in height. In virtue of completely high weathered zone and unfavorable soft structural plane and irrational construction procedure such as supports, as well as subject to rainwater and groundwater, tensile crack and landslide occur along soft structural plane of local sections. In order to ensure the safety of the project and the slope, anti - slide piles shall be adopted for comprehensive reinforcement to achieve a good effect.
